I have been looking to buy a thick fleece for awhile but it is clear most fleece nowadays is thin, even at Polartec's 300 weight. Kuhl's sweater is thicker than most and really well constructed. Why they stopped making this is beyond me, but you can still find this on 6pm Amazon etc. If you are looking for a sporty yet functional fleece to layer, then you should definitely look up this puppy.
